ANTIRAT'TLING DEVICE Fon STORM WINDOWS'. l

. Application fled February 20,' i928.A Serial No. 255,757.

My invention relates to an anti-rattling device for storm windows of the type hinged at the top and adapted to swing out and be held in open position with the lower edge away from the window fra-me. The main object of :the invention is to provide a simple, efficient and inexpensive device in the form of a. spring device which engages a storm window bracket arm and a part of a window frame under tension in such a manner that rattling of parts ordinarily caused by the elements is entirely eliminated.

In the accompanying drawing, Fig. 1 is a vertical sectional elevation o the lower portion of a window frame andthe lower part of a storm window being held outwardlyof the window frame and my device in operative position.

Fig. 2 is an approximately full size front view of my device looking as in direction of arrow A in Fig. 1, and Fig. 3 is a side elevation of Fig. 2 as seenlooking toward Fig. 2 from the left.

Referring to the drawing by reference numerals the window frame shown in cross section comprises the usual sill 5, side frame 6 and window-parting strip 7, 8 is the lower and regular slidable sash. 9 is the vertical strip comprising a stop for the inner edge of a st-orm window 10 to bear against when in closed position.

My anti-rattling device is particularly designed for the type of storm window bracket comprising, a pivot bracket 11 fixed one to each Yside member of a storm window and to which is pivotally secured as at 12 a brace bar 13 of flat bar stock as shown, said bar being loosely slidable' through a slot of another fixed bracket 14 secured on the vertical side frame 6 of the window. The free end of bar 13 is usually bent inward as 13B to provide a finger hold and also serve as a stop to limit outward movement of the storm window and such bar is usually provided with a downward notch 13N to engage the notched part of bracket 14 when the member 13B is close to said bracket, as best shown in Fig. 1. It is obvious that when the bracket device described is in the position holding the storm 5.o window out from the wall, any wind or comparatively light air currents will shake the storm window and cause the brace 13 to rattle in the bracket 14, creating undesirable noise particularly at night when a storm window is usually wanted open but at such times being oppositeends of which extends radially and 1n opposite directions two

arms

15A and 15B of which 15A is the front arm. The front end of said arm 15A isformed with an upward extension 15A at right angles to the arm and the said extension formed with a hook 15A opening downwardly.

mally in obtuse angled position relative to each other when the spring is inactive (see vfull lineposition of arms in' Fig. The

free end of arm 15B is formed with a trans-` verse elongated catch member 15B in a plane about radially out from the center of the coils 15 said catch member being preferably a formation of the wire in two parallel parts as shown in Fig. 1 and the extremity of the wi re preferably formed in a linger engaging loop 15B In the use of my device the hook 15A of the front arm is simply engaged over the top edge of the bar 13, arm extension 15A extenolingk downwardly and arm 15A rearward- Vly with coil 15 placed immediately below and inwardly of bracket 14 with arm 15B extendving inwardly and up. Then the operator simply presses against member 15B outwardly until the double wire arm 15B is in a plane just outwardly of the window frame 6 at which time the operator presses outwardly so that arm 15B can be released and member 15B will engage and be spring pressed against the outer surface of the upright window frame. As the

arms

15B and 15A are thus sprung toward each other against the action' of spring 15 it is obvious that arm 15A bears down on bracket arm 13 and holds it solid kand in non-rattling position in bracket 14.

The device may also be designed in such proportions that when in operative position as described arm 15B will engage the rear part of linger hold 13B of bar 13 and thus preventing any endwise movement of the bar (see Fig. 1).

I claim:

The rear arm 15Bmay be longer than the front one and both nor-' 1,. An anti-rattling device for a storm window hingedly suspended from its upper edge and having a brace bar pivotally connected to the innersideofthestormwindow and slidable through a bracket fixed in the window frame,

said device comprising a helical coil spring,

- two arms formed integral with said coils and A extremity ofone arm to engage the upper edge portion of the brace bar outwardly of the window frame bracket, and-means on the eX- tremity of the other arm to engage an upri ht.

part of the window frame above said brac et 10 when said arms are sprung toward each other.

2. The structure specified in claim 1 in .which said armsare adapted to be sprung toward each whenwin upright plane, and said means on the latter arm for engaging the Y Window frame comprises an integral part of said arm extending vtransversely sideways from the arm` to engage the window framek and a linger pressing member formed onrsaid part for the purpose described.

In testimonyl whereof I affix my signature.
